Fertilization of the ovum takes place in which part of the fallopian tube?

a. Interstitial portion
b. Ampulla
c. Isthmus
d. Infundibulum

Question 2

The nurse is monitoring the urine-specific gravity and pH of a child receiving chemotherapy. The nurse will try to maintain the urine values at:

1. Specific gravity 1.030; pH 6.
2. Specific gravity 1.030; pH 7.5.
3. Specific gravity 1.005; pH 6.
4. Specific gravity 1.005; pH 7.5.

Answer to Question 1

B
Feedback
A The interstitial portion runs into the uterine cavity. This area is too close to the
uterine body for fertilization to occur; it would lead to improper placement for
implantation.
B The ampulla is the wider middle part of the tube lateral to the isthmus and is
where fertilization occurs.
C The isthmus is the narrowest portion of the tube.
D The infundibulum is the end of the tube that opens into the abdominal cavity.
Fertilization at this area may lead to an abdominal pregnancy.

Answer to Question 2

Rationale:
1. Because the breakdown of malignant cells releases intracellular components into the blood, and electrolyte imbalance causes metabolic acidosis, the urine-specific gravity should remain lower than 1.010 and the pH at 77.5. A specific gravity higher than 1.010 can mean fluid intake is not high enough, and a pH lower than 7 means acidosis.
2. Because the breakdown of malignant cells releases intracellular components into the blood, and electrolyte imbalance causes metabolic acidosis, the urine-specific gravity should remain lower than 1.010 and the pH at 7 to 7.5. A specific gravity higher than 1.010 can mean fluid intake is not high enough, and a pH lower than 7 means acidosis.
